Don't annoy them

Here are some more cape buffaloes at the waterhole.

These animals are nasty buggers. Cape buffaloes kill more humans each year in Africa than any other animal. If you come across a lone bull, he will undoubtedly charge. Unless there is a handy tree and you are a good climber, this will not end well for you.
